Description

Technical Field

[0002] A pressure sensor is a device or apparatus that can sense pressure signals and convert them into usable output electrical signals according to certain rules.

[0003] During the production process of pressure sensors, the sensitive components and related circuits of the pressure sensors need to be protected and fixed, that is, they need to be encapsulated through a shell. After encapsulation, the outer surface of the pressure sensor needs to be tested for the packaging effect, and a microscope is used to check whether there are cracks, damage, and the quality of the solder joints on the outer surface.

[0004] The existing pressure sensor detection tooling usually uses a microscope to observe its outer surface, and the pressure sensor is placed on the observation table of the microscope for observation. Since the outer surface of the pressure sensor is irregular in shape, it is easy to shake when placed on the observation table, and it is not placed properly, which makes it difficult to effectively observe the required part when observing with a microscope. In view of this, we propose a pressure sensor detection tooling. Utility Model Content

[0029] In the embodiment of the utility model, the two support rods 205 are inserted into the column bins 203 of the corresponding two support tubes 202, and the height is adjusted, and the threaded rod 204 is further rotated to make the rod head of the threaded rod 204 move toward the inside of the column bin 203 until it contacts the circumferential side wall of the support rod 205, and the support column 205 is clamped and fastened. The installation is simple and fast, and the height adjustment is convenient. Further, by pulling the clamping block 1 211 to move along the two sliding rods 212, the clamping block 1 211 is moved away from the clamping block 213, and the pressure sensor is placed between the clamping block 1 211 and the clamping block 213. The clamping block 1 211 is clamped by two springs 209. The elastic force is generated to push the clamping block 1 211 to move toward the side wall of the pressure sensor, and the pressure sensor is clamped and tightened in cooperation with the clamping block 213, which is beneficial to clamping and positioning the pressure sensor and is convenient for detection and observation. Furthermore, according to the location of the pressure sensor to be detected, the fixed side plate 208 is rotated to rotate the rotating rod 1 207 and the rotating rod 215, thereby driving the pressure sensor to rotate. Then, the insert rod 218 is inserted into the insert hole 220 on the side wall of the turntable 217 and extended to the rod hole 219 on the side wall of the limiting block 216 to limit the rotation of the turntable 217, thereby further limiting the rotation of the pressure sensor and keeping the pressure sensor at a fixed angle for detection and observation.

[0030] Specifically, a column bin 203 is provided on the top surface of the support tube 202 , and a support column 205 is provided in the column bin 203 .

The rotation is restricted by inserting the insertion rod 218 into the insertion hole 220 and extending it to the rod hole 219. The eight rod holes 219 can be set at eight observation angles.

[0035] Working principle: This embodiment provides a pressure sensor detection tooling. When in use, the two support rods 205 are inserted into the column bins 203 of the corresponding two support tubes 202, and the height is adjusted. The threaded rod 204 is further rotated to make the rod head of the threaded rod 204 move toward the inside of the column bin 203 until it contacts the circumferential side wall of the support rod 205, and the support column 205 is clamped and tightened. Further, the clamping block 1 211 is pulled to move along the two sliding rods 212 so that the clamping block 1 211 is away from the clamping block 213, and the pressure sensor is placed between the clamping block 1 211 and the clamping block 213. 209 generates elastic force on the clamping block 1 211, pushing the clamping block 1 211 to move toward the side wall of the pressure sensor, and cooperates with the clamping block 213 to clamp and tighten the pressure sensor. Further, according to the location of the pressure sensor to be detected, the fixed side plate 208 is rotated to rotate the rotating rod 1 207 and the rotating rod 215, thereby driving the pressure sensor to rotate. Then, the insert rod 218 is inserted into the insertion hole 220 on the side wall of the turntable 217 and extended to the rod hole 219 on the side wall of the limiting block 216 to limit the rotation of the turntable 217, thereby further limiting the rotation of the pressure sensor and keeping the pressure sensor at a fixed angle for detection and observation.
